FGFBP2 Protein, Human (sf9, His)

The FGFBP2 protein is secreted by cytotoxic T lymphocytes and binds reversibly to acidic and basic fibroblast growth factors. It also binds to the basement membrane glycans. FGFBP2 is highly expressed in human malignant cells and normal tissues and is a potential prognostic biomarker for tumors. FGFBP2 Protein, Human (sf9, His) is the recombinant human-derived FGFBP2 protein, expressed by Sf9 insect cells , with C-His labeled tag.

Fibroblast growth factor binding protein 2 is a protein encoded by the FGFBP2 gene in humans. The FGFBP2 protein is secreted by cytotoxic T lymphocytes and binds reversibly to acidic and basic fibroblast growth factors. It also binds to the basement membrane glycans. FGFBP2 is highly expressed in human malignant cells and normal tissues and is a potential prognostic biomarker for tumors^[1][2].

Full Length of Mature Protein

Approximately 22.6 kDa.

Greater than 90% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 20 mM Tris, 300 mM NaCl, 10% Glycerol, pH 8.0. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
